A failed criminal, Drury Walker, while incarcerated in Arkham Asylum was reading an article in the Gotham Times about Batman. He decides to remake himself as an "anti-Batman", and contract himself out to the Gotham underworld. Upon his release from Arkham he digs up the money that he had stolen over the years in his criminal endevours and establishes himself as the millionaire philanthropist Cameron Van Cleer; and eventually befriends Bruce Wayne.
All the while building his own versions of all of Batman's equipement. Such as the Mothmobile, even providing the criminals of Gotham with an infrared "Moth Signal"
Originally using a cape, he later designed a flight pack. He is equiped with a "Cocoon Gun"
Wings are custom made, there is a vinyl strap attached from the holster to the belt. On a side note there is a Charaxas on the way :)
